Just came across this: http://www.genesi.lu/

Appears to be a new PPC based platform with published specs - would be
great to have ROS running on this!

Cheers

Yes, the Pegasos boards look great! Have a look at this:
http://www.pegasosppc.com/

But I have to remind you that there are _no_ usable development tools
available. We will have to add little-endian PPC-PE support to GCC and
Binutils because it was either removed (GCC) or suffers from heavy bit-rot
(Binutils). This is not an easy task when you're neither a PPC-Guru nor a
GCC/Binutils-Guru.

Right. The only other option is to add a ELF loader to ntosknrl and
ntdll and then build all of ReactOS as ELF Winelib binaries. I have
looked at this quite a bit and even have a bug for it bugzilla. We have
the needed tools to support a ELF build of ReactOS but we need someone
to write the binary loader. I have spoken to Alexandre about it at
length and Blight did some research in to this....needless to say we
have not made much progress as of yet.

I am afriad our only hopes of porting to other platforms with PE are
arm-wince-pe and sh4-pe both of which are still supported by mainly GCC
for embedded development.

Thanks
Steven

Adding support to load (map) ELF files to ntoskrnl is not a big problem 
I think (I have already done this and it should work)
Problems which I had was that normal ELF files do not contain an 
optional header which we need (it contains for example the required os 
and subsystem version and subsystem type) - this is what wingcc can be 
used for I think.
I have also had problems with building our libraries in ELF format to 
link some ELF test-app against, maybe this is easier with wingcc.

Maybe if I try again with the WINE tools I can get further... If anybody 
else wants to try I can send a patch for ELF support in ntoskrnl.

Yes post the patch.

I have a CD with MetaWare's High C/C++ PPC for dos. (cant find it ATM)
It supports ELF/DWARF. I think using ELF is way to go.

The nice thing about going ELF is that it will let us port to every
platform currently supported by gcc. Eric had some objections to it
before but if we only do a ELF build on i386 for testing and do not
release it to the public I dont really see anything wrong with allowing
ELF for other hardware.

Thanks
Steven

Great. I will try and help with this.

Can you attach your patch to this bug?
